Basic Math Examples

$6 d^{2} - 7 d + 8 + (- 4 d^{2} + 9 d - 5)$

Step 1

Remove parentheses.

$6 d^{2} - 7 d + 8 - 4 d^{2} + 9 d - 5$

Step 2

Subtract $4 d^{2}$ from $6 d^{2}$ .

$2 d^{2} - 7 d + 8 + 9 d - 5$

Step 3

Add $- 7 d$ and $9 d$ .

$2 d^{2} + 2 d + 8 - 5$

Step 4

Subtract $5$ from $8$ .

$2 d^{2} + 2 d + 3$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
